WRENCH.

Specification of Letters Patent.

Application filed June 11. 1908. Serial No. 437,981.

No. 908,677. Patented Jan. 5, 1909.

To all whom it may concern: l. ber 1 is formed with a socket 6preferably Be it known that I, ROBERT WILIJAM tapering somewhat inwardlywith its inner JONES, a citlzen of the United States, residi end of moreacute meeting incllned walls ing at London, in the county of Madison and1 than are its opposed walls, as at 7, said socket State of Ohio, haveinvented certain new and i having inwar ly extendin contracted porusefulImprovements in Wrenches; and I do tions 8, the purpose of whic will beapparent declare the following to be a full, clear, andl later. exactdescription of the invention, such as i The handle member 3 which ispreferably will enable others skilled in the art to which of anyrequired length for convenience for it appertains to make and use thesame. grasplng, has its inner portion provided with i y inventionrelates to improvements in slightly inwardly inclined lateral ed eswhich wrenches. conform to the corresponding wal s of the It has for itsobject to provide a simple, Socket of the member 1 and the intermediateinexpensive and efiective contrivance of this portion of its extremeinner end recessed or cut out as at 9 to conform to and receive thebolts and for manipulating pi es or other cylindric objects in a readyan expeditious manner.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arran ement ofparts, as will be more why descri ed and particularly pointed out in theap ended claims.

11 the drawings illustrating the preferred form of my invention :Figure1 is aside elel vation thereof; Fig. 2 is a similar view of the samewith the handle member removed a short distance from the member equippedwith jaws, a portion of the device being removed to disclose moreespecially the interior of the handle-receiving socket in the memberprovided with jaws; Fig. 3 is a vertical longitudinal section of thewrench taken on line 33 of Fig. 2; Fig. 4 is a modification thereof withthe parts adapted more particularly for use as a pipe wrench.

In practicing my invention I provide a member or part 1 equipped withjaws 2 and the handle member 3 adapted for suitable attachment to thefirst referred to member and its ready removal therefrom as in efiectingready conversion of the device from a nut or bolt wrench into a pi ewrench or for application to other cylindrical objects where its use maybe required.

The member 1 which is preferabl of general rectangular outline, butslight y tapering in longitudinal direction, has its jaws 2, which arearallel for the greater portion of their lengt s upon op osite surfaces,formed with inclined or angu ar surfaces 5 inwardly from their parallelo posed faces in order to accommodate the di erent outlines of diflerentshaped nuts or bolt heads. Said memhandle a so having extending beyondits tapered recess, terminals 10 to enter the corresponding portions ofsaid socket.

It will be seen that the handle, as it is inserted in place in themember 1, will be wedged in a fixed effective position, thus dispensingwith additional means for effecting that purpose and whereby the handlemember may be readily removed and inserted without dis lacing othermeans of fastening. Also, it wil be noted that by means of thisarrangement, the handle and member having the jaws for engagement withthe object to be mani lated may be readily separated or disassociated asin effecting the conversion of the device according to its intended useas above described.

In the modification as designated byFig. 4, the member 11 of generaloutline with the member 1 has its corresponding jaw members 12.ada tedfor apphcation to a pipe or other cylin rical object, the inner faces ofsaid jaws being straight and somewhat curved respectively in order toobtain the requisite leverage upon the object or pipe manipulated.

The rectilinear or straight surface of one jaw is preferably formed withnotches or serrations 13 and which surface may be formed of a piece ofsteel set into the respective jaw.

It will be understood that the wrench as a whole may be made ofmalleable metal'or steel as desired. Also, it will be noted that a verysimple, inexpensive and efl'ective instrument is provided by reason ofthe foregoing construction and arrangement of parts for its intendedpurpose.

From the fore oing description taken in connection with t e accompanyingdrawings,

acute tapered portion of said socket, said the construction andoperation of the invention will be readily understood without requiringa more extended ex lanation,

Various changes in the orm, proportion and the minor details ofconstructlon may be resorted to without departing from the principle orsacrificing any of theadvantages of the invention, as defined in theappended claims.

I claim as my invention 1. A device of the character describedcomprising a jaw equipped meinber havin a socket therein with laterallytapering walls, said socket having at its extreme inner end contractedterminals and intermediate said terminals meeting inclined walls, theirpoint of convergence being about central of the socket.

having a socket therein of general inwardl;

tapering contour with its inner surface formed with'nieetim inclinedsurfaces forming an apex central of the bottom of said socket, and ahandle member having a corresponding recess at its inner end forengagement with the inner bottom surface of said socket.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ROBERT WILLIAM JONES.
